CHARGING AND DRAWING ()F'POTTERS OVENS.

I Specification of Letters Patent. 5 Patented J uly 24, 1917.

7 Application filed September 14, 1913. Serial No. 120,043.

To all whom it may concern:

Be it known that I, MARTIN PENNINGTON Fnnnnrrrouorr, a subject of theKing of Great Britain and Ireland, residing at 77 Chaplin road Normacot,Stoke-upon-Trent, England, have invented certainmnew and usefulImprovements Relating to the Charging and Drawing of Potters Ovens, ofwhich the following is a specification.

'In the manufacture of pottery the ware is placed, for the firingprocess, insaggars which are stacked in the ovens. The charging orplacing of the saggars in the oven and they subsequent removal ordrawing of the same from the ovens is a long and laborious process.

My invention comprises for provision within the oven a portable andcollapsible vertical gauntree fitted with lifting and lowering devicesor hoists, together with one or more adjustable horizontal arms orstages whereby the saggars can be conveyed between the hoist and anypart of theoven interior. 1 V

In the accompanying sheets of explanatory drawings f Figures 1,. 2 and'3 illustrate diagrammatically by front view, side view and planrespectively a charging and discharging'apparatus constructed inaccordance with this '-'-'ad acent to one of the arms or stages toinvention.

In carrying the invention into effect as shown, the vertical gauntreecomprises a frame or standard a made up of steel bars of angle or othersection, or it may be made from steel tubing. To permit of its beingreadily placed within or withdrawn from the oven, the gauntree is madeup in any convenient manner of detachable parts which can be readilyconnected or disconnected.

The raising and lowering of the saggars within the oven is effected bymeans of cages b which are operated by hand or power driven liftmechanism of any convenient type. Preferably one pair of cages at leastare employed with each gauntree and are arranged to balance, or so thatthe one ascends while the other descends. Preferably the cages come to acommon position at the bottom of the gauntree owing to the narrowness ofthe doorway through which the saggars pass into or out-of the oven. Toefiect this the cage guides are suitably constructed so that they cometogether'at the lower ends.

For enabling the saggars to be withdrawn from or put upon the 'gauntreecages at convenient heights or'lev'els and tobe placed 1 at or drawnfrom all parts of the oven interror, transport arms or stages 0 areproyided upon the gauntree. Each arm or stage 1s constructed as'shown insections which can telescope. Also the section adjacent to thegauntreeis made to slide thereon. This 7 section is constructed from twoparts with curved abutting ends as illustrated so that the main portionof the stage canbe swung laterally relatively to the gauntree'.Preferably vertical adjustment is effected by winch actuated ropes (Zfrom which the arms are suspended. 'The outer ends of the arms aresupported on standards 6 which are oven, being set up in a positionpreferably just within the doorway or admission aperture. As the saggarsare placed by'placers or operatives one upon another the stack readilyadj ustedto any height or positionin I assembled or exte'ndedfor servicewithin the or pile gradually rises up from the oven floor until itbecomes out of convenient reach. The placer then ascends the gauntreeand takes up a position upon a platform which the saggars are raised bythe gauntree. By passing from stage to stage the oven is thus charged,when the gauntree is withdrawn. In like manner when the saggars are tobe drawn from the oven the gauntree is again brought into service with 1in the oven.

The invention is not limited to any particular manner of constructingthe gauntree and arms and supports for the outer ends of the latter, orthe different actuating mechanisms. drawings indlcate the essentlalfeatures and detalls may be varled to meet requirements.

The foregoing description and the Having thus described my inventionwhat i I claim as new and desire to secure by Letters Patent is a 1.Portable means for charging and drawing saggars into and out of pottersovens, comprising a collapsible vertical gauntree, a hoist in saidgauntree, and a horizontal arm attached to the gauntree and movablevertically thereon, substantially as described.

2. Portable means for charging and drawing saggars into and out ofpotters ovens,

comprising a collapsible vertical gauntree, a hoist in said gauntree,and an extensible horizontal arm attached to the gauntree and movablevertically thereon, substantially as described.

3. Portable means for charging and drawing saggars into and out ofpotters ovens, comprising a collapsible vertical gauntree, a hoist insaid gauntree, and a plurality of horizontal arms attached to thegauntree and movable vertically thereon, substantially as described.

4. Portable means for charging and drawing saggars into and out ofpotters ovens, comprising a collapsible vertical gauntree, a hoist insaid gauntree, a horizontal arm attached to the gauntree and movablevertically thereon, and a collapsible support for .the outer end of thearm, substantially as described.

5. Portable means for charging and drawing saggars into and out ofpotters ovens, comprising a collapsible vertical gauntree, a hoist insaid gauntree, a horizontal arm attached to the gauntree and movablevertically thereon, a collapsible support for the outer end of the arm,and raising and lowering mechanism for the arm, substantially asdescribed,

' 6. Portable means for charging and drawing saggars into and out ofpotters ovens, comprising a collapsible vertical gauntree, a hoist insaid gauntree, a horizontal arm attached to the gauntree, a collapsiblesupport for the outer end of the arm, and an adjustable suspensorydevice for the arm attached to the gauntree and the support,substantially as described.

7. Portable means for charging and drawing saggars into and out ofpotters ovens,

comprising a collapsible vertical gauntree,

a pair of hoists in said gauntree, guides for the hoists uniting in acommon position at the lower end of the gauntree, and a hori zontal armattached to the gauntree and movable vertically thereon, substantiallyas described.

8. Portable means for charging and drawing saggars into and out ofpotters ovens,

comprising a collapsible vertical gauntree, a hoist in said gauntree, ahorizontal arm attached to the gauntree and movable vertically thereon,and means permitting a lateral swing of the arm relatively to thegauntree, substantially as described.

9. Portable means for charging and drawing saggars into and out ofpotter-s ovens, comprising a collapsible vertical gauntree,

a pair of hoists in said gauntree, guides for v Copies of this patentmay be obtained for five cents each, by addressing the Commissioner oflatents, Washington, D. C.
